Controlling a Group of Unmanned Aerial Vehicles for Delivery of Goods

2. The method of claim 1, wherein the drag data comprises at least one of a predefined value for the one or more UAVs, or a measured value by or for the one or more UAVs.

3. The method of claim 2, wherein the predefined value is obtained as a function of the goods carried by the one or more UAVs and/or is indicative of a frontal area of the one or more UAVs when carrying its goods.

4. The method of claim 2, wherein the measured value is at least one of a travel speed of the one or more UAVs, an air speed at the one or more UAVs, a wind speed and/or wind direction, an acceleration of the one or more UAVs, an orientation of the one or more UAVs in relation to a reference plane, or a distribution of propulsion energy to spatially separate propulsion elements on the one or more UAVs.

5. The method of claim 1, wherein said determining the respective relative position and said controlling are performed continuously or intermittently while the UAVs are organized in the group.

10. The method of claim 9, wherein the flight formation is selected among a set of predefined flight formations.

16. The method of claim 12, wherein the travel capacity data is indicative of a remaining flight range of the one or more UAVs at a defined time point.

17. The method of claim 1, wherein said obtaining the drag data, said determining the respective relative position, and said controlling are performed by a master UAV in the group.

18. A control system configured to perform the method of claim 1 and comprising a communication device for communicating with at least one UAV in the group.

19. A non-transitory computer-readable medium comprising computer instructions which, when executed by a processing system, cause the processing system to perform the method of claim 1.
